Colonization of endophytic Bacillus velezensis PEBA20 in eucalyptus and its biocontrol effect against eucalyptus bacterial wilt.
Findings indicate that B. velezensis PEBA20 has a strong capacity for endophytic colonization, disease suppression, and plant growth promotion, providing both a promising bacterial resource and a theoretical basis for the biological control of vascular wilt diseases caused by R. pseudosolanacearum.
